Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an escalator device, and more particularly to an escalator device that can stably transport vehicles such as wheelchairs and carts.

[Conventional technology]

As shown in Figure 1, a general escalator device has a main body part 1 that supports the entire escalator.
A pair of balustrades 2 erected on both sides of the main body portion 1, a handrail 2a running along the periphery of the balustrade 2, and a handrail 2a running at the same speed as the handrail 2a between the pair of balustrades 2. It is equipped with steps 3 for moving. The step 3 is a horizontal tread 3.
a, and a riser 3b that is connected to the tread surface 3a and extends downward, and further includes the roller 3c and a rear roller 3d in order for the step 3 to run.

[Problem to be solved by the invention]

The escalator device was not capable of transporting wheelchairs or shopping carts.

An object of the present invention is to provide an escalator device that can stably transport transport vehicles such as wheelchairs and carts.

[Means to solve the problem]

In order to achieve the above object, the present invention provides at least one of a plurality of steps with a specific step, a movable tread that can move upward on the specific step, and a rising mechanism that moves the movable tread upward. was established.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. In this embodiment, in an escalator equipped with a plurality of steps 3 having a well-known configuration, one or more specific steps 4 are provided in a row of the steps 3. The basic structure of this specific step 4 consists of a horizontal tread 4a and a riser 4b, and a front roller 4.
c, guide rails 5a, 5 by rear roller 4d
It is the same as the well-known step 3 mentioned above in that it runs on the above-mentioned step b. However, the specific step 4 is significantly different from the step 3 in that the movable tread 6 is separated leaving the peripheral edge of the tread 4a. This separated movable tread 6 is supported by a support 7, and although not shown, is guided by this support 7 so that it can move upward. This support body 7 is then moved upward by a lifting mechanism 8. The lifting mechanism 8
consists of a roller 9 provided at the lower end of the support 7, and a guide rail 10 facing the roller 9 and laid in a section where it is desired to raise the movable tread 6,
When the roller 9 comes into contact with this guide rail 10, the support body 7 is raised, and the movable tread surface 6 is raised by a dimension h. This dimension h is set to be the same height as the tread of the step 3U adjacent to the upper side, and the wheelchair K is mounted horizontally astride the tread of the step 3U and the movable tread 6. As a result, the space for wheelchair K to ride is approximately twice as long as the length of the movable tread 6 of specific step 4 is added to the length of the tread of step 3U, which is approximately 400 mm, and therefore the space for wheelchair K to ride is secured. It is safe because it is possible for K to get on the vehicle and the riding position can be maintained horizontally.

By the way, although the above-described embodiment has been described with respect to getting in the wheelchair K, it is of course applicable to getting in not only the wheelchair K but also a transport vehicle such as a cart. Furthermore, although the lifting mechanism 8 is made up of rollers 9 and guide rails 10, a lifting mechanism such as a hydraulic mechanism or a spring mechanism may be installed below the movable tread 6 to raise it. Moreover, although the movable tread surface 6 is separated from the tread surface 4a leaving only the peripheral edge thereof, the entire surface of the tread surface 4a may be raised.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to obtain an escalator device that can stably transport a transport vehicle in a horizontal position while straddling two adjacent steps.
